Caught in the Act!

 Mary-Kate Olsen, making out with her artist
boyfriend Nate Lowman at New York's Indochine. The two even had an audience. Says a source: "The
restaurant was so busy since it's [bargain-priced] Restaurant Week."

 Much more low-key, Johnny Depp, ate a quiet
poolside lunch at Los Angeles's Sunset Tower Hotel. Sharing his meal in
cabana with an older gentleman, the actor turned more private as more diners
arrived. "He just stood up and casually dropped down the flap of the
cabana," an onlooker tells us. Among those deprived any further glimpses
of the actor, a curious Nicole Richie, who was dining at
a nearby table with a female friend.

 On a break from a shopping trip with mom Tish, Miley Cyrus stopped into Katsuya Glendale for lunch on the restaurant's
balcony. The mother-daughter pair ate tempura and saved room for dessert
– mochi ice cream!

 Neil Patrick Harris and boyfriend David Burtka, looking to expand their collection at ART LA, one of the biggest art
shows in Los Angeles. The two browsed the more than 60 exhibitor booths – including paintings, sculptures and light installations – set up inside
a converted hangar at the Santa Monica Airport. Also there:
Keanu Reeves and Tobey Maguire, who made a
purchase.

 He's married, but that didn't stop the ladies from ogling Clive Owen as he partied at West Hollywood's Apple Lounge. "Girls were
actually lining up to meet him," says an onlooker. "It was crazy!" Also at
Apple that night: 90210's AnnaLynne McCord, who huddled
with her sister for warmth in an outdoor cabana, and castmate Josh Henderson.
